Abstract

The experiment was conducted at the sick plot, Pulses Research Centre, Ishurdi, Pabna, Bangladesh during two consecutive years of 2011-12 and 2012-13 to screen out the effective BARI Rhizobium Biofertilizers against foot and root rot of lentil. Seven BARI Rhizobium strains viz. BARI LE 715, BARI Rlc 103, BARI Rlc 140, BARI Rlc 107, BARI Rlc 105, BARI Rlc 138 and BARI Rlc 101 were used as treatments. In 2011-12, foot and root rot incidence ranged from 9.66-29.95%, while the lowest incidence was recorded in BARI LE 715 which was followed by BARI RLC 140, BARI RLC 107 and BARI RLC 138; and the highest incidence was recorded in untreated control. BARI LE 715 gave the highest plant survival (90.34%) and control treatment gave the lowest plant survival (70.05%). BARI LE 715 treated plots reduced maximum foot and root rot incidence (67.75%) over untreated control. Similar trends of the results were observed in 2012-13. The highest yield 2153 and 2016 kg/ha was obtained from BARI LE 715 in 2011-12 and 2012-13, respectively, and the lowest of these parameters were obtained from untreated control for both the years.
